Cloud-based scanning systems and remote image processing methods

ABSTRACT

A cloud-based document scanning system includes a cloud computing platform having a cloud computing application and a cloud storage system. The system further includes a scanning device communicatively coupled over a network to the cloud computing platform, the scanning device configured to: accept a set of documents; generate a set of digital image files corresponding to the set of documents; store the set of digital image files; and upload the set of digital image files directly to the cloud storage system. Upon receiving a request from the scanning device, the cloud computing application is configured to: access the set of digital image files; apply image processing operations to the set of digital image files in accordance with a plurality of image processing parameters, generate a portable document format document based on the processed image files, and send the portable document format document to a user-selected destination.

TECHNICAL FIELD

The present invention relates, generally, to document scanning technology and, more particularly, to distributed cloud-based image processing and document management systems.

BACKGROUND

Technological improvements in the fields of cloud storage and mobile computing systems—together with a renewed emphasis on reducing paper consumption—have driven an increased interest in paperless systems by both consumers and businesses. Such paperless paradigms, which generally involve generating and storing digital versions of physical documents, provide numerous advantages, such as ubiquitous access to information, improved security (through strong encryption), automated data capture, reduced overhead, and document consolidation.

While paperless systems are advantageous in many respects, a number of significant challenges remain. For example, traditional scanning systems, such as those incorporated into conventional copy machines, tend to be bulky, expensive, and difficult to deploy. Most, in fact, require dedicated computer for set-up and operation. Furthermore, such systems do not provide a streamlined work-flow, and generally provide very few delivery options for scanned documents (i.e., typically only e-mail or a designated network folder). In addition, traditional scanning systems lack significant document editing functionality at the scanner interface.

Systems and methods are therefore needed that overcome these and other limitations of the prior art.

DETAILED DESCRIPTION OF PREFERRED EXEMPLARY EMBODIMENTS

The present invention relates to improved, easy-to-use, cloud-based systems and methods for scanning, securely storing, managing, and retrieving digital documents. In accordance with various embodiments, at least a portion of the image processing is performed by a cloud-based application, rather than at the scanning device itself. The resulting electronic images can, in a streamlined fashion, be delivered to a variety of destinations, such as e-mail addresses, fax numbers, a local USB drive, or a cloud service (e.g., Raven Cloud, Google Drive, Dropbox, Box, Evernote, or the like). In that regard, the following detailed description is merely exemplary in nature and is not intended to limit the inventions or the application and uses of the inventions described herein. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.

Referring now to FIG. 1, a cloud-based document scanning and management system (or simply “scanning system”) 100 in accordance with various embodiments will now be described. As a preliminary matter, it will be understood that system 100 may incorporate a number of conventional network components, such as switches, routers, hubs, bridges, access points, gateways and the like. In the interest of clarity, such conventional components have not been illustrated in FIG. 1.

In general, system 100 includes a document scanning device (“scanning device” or simply “scanner”) 110 communicatively coupled over a network 150 (e.g., the Internet) with a cloud computing platform 140 and one or more third-party systems 147 (representing, for example, third-party servers or APIs). Various network destinations 160 representing potential endpoints for transmitting the final digitized documents are communicatively coupled to cloud computing platform 140. For example, destination 161 may correspond to an e-mail server, destination 162 may correspond to the Raven Cloud, destination 163 may correspond to Dropbox, destination 164 may correspond to Google Cloud Drive, and so on.

Scanner 110 generally includes a scanner body 114 enclosing a combination of hardware, firmware, and software configured to receive one or more documents 120 (e.g., printed pages, receipts, tickets, photos, or any other substantially flat object) and produce a corresponding digitized representation, which may take a variety of forms as described in further detail below. In one embodiment, scanner 110 incorporates an automatic document feeder (ADF) that feeds individual pages to a one or two-sided image sensor (e.g., a contact image sensor (CIS)) having an LED light source and a suitable optical resolution (e.g., about 600 dpi).

Scanner 110 includes a USB interface 116 or the like configured to accept a standard flash memory drive for storing digitized documents (i.e., as one selectable destination). Scanner 110 also includes various indicators and user interface components, such as a touch screen 112 and one or more buttons or other user-actuatable components 113. In one embodiment, touch screen 112 is a 7-inch color LCD, and buttons 113 include a “screen saver” button configured to selectably place touch screen 112 in a screen saver mode whereupon it will not accept input from the user. While not illustrated in FIG. 1, scanner 110 may also include a power cable input and an Ethernet (RJ-45) jack for wired connection to network 150 (as an alternative to WiFi, as described below).

With reference to the inset shown in FIG. 1, scanner 110 includes, typically within housing 114, a processing module 170 comprising various electronic components and software configured to accomplish the functions described herein. Thus, for example, processing module 170 includes a user interface module 171 (including, for example, touch screen 112), a central processing unit (CPU) or other processor 173, one or more memory components 172, one or more storage components 174 (e.g., a hard drive, flash memory, or the like), a power supply 176, and network interfaces 175 for connecting to network 150. Network interfaces 175 may include, for example, an Ethernet interface as well as a Wi-Fi interface (e.g., an IEEE 802.11 b/g/n compliant interface). While not illustrated in FIG. 1, processing module 170 will typically also include suitable interfaces to the hardware components provided within scanner 110, such as the document feeder, the image sensor, rechargeable battery pack, and the like.

Various software components are stored (e.g., at 172 and 174) for execution by processor 173. For example, in one embodiment scanner 110 comprises two primary software modules: a main scanner application that manages user interaction, and a middleware layer that operates behind the scenes between the main scanner application and the scanner hardware. The middleware layer may include one or more plug-ins that communicate with the scanning hardware (e.g., document feeder, scanner optics, etc.). For example, when a user initiates a scan (via touch screen 112), the scanner app instructs a plug-in to cause the scanning hardware to initiate a scan.

With continued reference to FIG. 1, cloud computing platform 140 generally includes a Raven API 141, a job processor 142, cloud storage 145 (for storing various data 181) and a serverless functions module 143.

Cloud functions module 143 includes “serverless” code segments that respond to events (captured by cloud computing platform) without requiring a managed runtime environment. In an illustrated embodiment, serverless functions 143 are implemented using Google Cloud Functions. The invention is not so limited, however. Other event-driven, serverless frameworks may be used, such as AWS Lambda or the like. Furthermore, the illustrated embodiments are not limited to event-driven software. Traditional runtime applications may also be used. Accordingly, the phrases “cloud functions” and “serverless functions” are used without loss of generality.

In contrast to serverless functions 143, job processor 142 comprises server-based software components that perform, in the background, much of the computationally complex tasks described herein, such as assembling and generating the finished PDF document. In one embodiment, for example, job processor 142 is implemented using Google Compute Engine. In one embodiment, job processor 142 is substantially a server-based duplicate of Raven API 141, configured to provide substantially the same functionality, as needed in appropriate contexts.

Raven API 141 comprises a set of software components, specifications, and communication protocols configured to respond to a defined set of requests. In one embodiment, Raven API 141 is implemented using a representational state transfer (REST) architecture implemented using the Google Cloud API framework. As will be discussed in further detail below, scanner 110 (including its main scanner application and middleware layer) will generally communicate directly with Raven API 141, while serverless functions module 143 will generally react to events that occur on platform 140 and/or within cloud storage 145.

Cloud storage 145 may be implemented as a datastore configured to store data generated by various components of system 100, including, for example, raw image data, optical character recognition (OCR) data, and thumbnail images. In one embodiment, cloud storage 145 is implemented using Google Cloud Storage. Raven API 141 may store certain data (e.g., page models 182 and OCR data) within its own database 148 (e.g., a MongoDB database), or may use cloud storage 145 (and/or other ancillary data structures) for this purpose. As described in further detail below, page models 182 include metadata describing the content of the final PDF document to be produced, such as the set of URLs used to store images within cloud storage 145, the document name, the location of thumbnails, extracted text, and/or parameters specifying any edits (zoom, crop, rotate, etc.) made by the user.

FIG. 2 is a flow chart illustrating a method 200 by which a user may interact with scanner 110 in accordance with various embodiments, and will be described in conjunction with the block diagram of FIG. 1. First, at 201, the scanner 110 is suitably connected to network 150 via, for example, network interfaces 175 (i.e., via Ethernet or Wi-Fi). As mentioned above, this connection may take place via one or more intermediate network components, such as modems, gateways, access points, switches, and the like.

Next, at 202, the user is asked to sign in or, if the user does not yet have an account, sign up for the system by entering the appropriate credentials (e.g., user name and password). These user credentials may also correspond to a particular cloud storage provider, such as the Raven Cloud Storage system. The user may also be provided with a free trial account at this time.

Next, the user selects the desired scan settings (203), and selects the destination (204) to which the finished document is to be sent. In one embodiment, for example, the user is prompted (via touch screen 112) to select: (1) number of sides (1-sided/2-sided), (2) color (full color, black and white, or greyscale), (3) quality (200 dpi, 400 dpi, 600 dpi), and (4) destination (e-mail, Raven Cloud, Google Drive, Dropbox, USB, etc.). With momentary reference to FIG. 5, one particularly intuitive user interface configuration that may be employed for this selection includes a display 500 including four large buttons: 501 (for “sides”), 502 (for “color”), 503 (for “quality”), and 504 (for “destination”, or “action”). Display 500 further includes a “scan” button 505 that can be used to initiate the scanning process, corresponding to step 205 in FIG. 2.

When the user initiates a scan (205), the scanner app requests, for example using a middleware plug-in prompted by the scanner app, that the scanner hardware actually perform the page scanning operation and conduct initial processing of the resulting image (206). The plug-in then informs the scanner that the scanned pages are stored locally in a designated folder. Subsequently, at 207, thumbnail images of the scanned page or pages are generated by scanner 110 for display on touch screen 112.

Continuing with step 208, the user is provided the opportunity to scan additional pages. If the user chooses to do so, then processing loops back to step 205; if not, then processing continues at step 209, wherein the user is presented with a user interface that allows the user to remove pages, reorder pages, edit pages, and/or combine pages within a single document. The user may also rotate, crop, or pan individual pages.

For example, referring briefly to FIG. 6, the user may be presented with a series of thumbnail images along with touch screen user interface 600 components that allow the user to combine, remove, and reorder individual pages. Similarly, as shown in FIG. 7, the user may be provided with user interface components (700) for rotating, cropping, and zooming in on a page alongside a relatively large thumbnail of the page being modified.

Referring again to FIG. 2, when the desired page operations have been completed, the user is provided the opportunity to name the document (210) and to change the destination (211). Subsequently, the document is transmitted (212) to the desired destination as described in further detail below.

FIG. 3 illustrates a scanner application and associated plug-in flow 300 in accordance with one embodiment. In this illustration, as indicated by the key at the lower right, the shading used in each block is related to the entity that performs or is the focus of that step—i.e., the Raven API 141, serverless function module 143, and job processor 142.

At 301, Raven API 141 receives a request from scanner 110 to upload a page or group of pages (identified by filename) to cloud storage 145 and requests an upload URL (302). Raven API 141 then creates and returns, for each scanned page, a page model (including page ID) along with an upload URL to the scanner in response to the upload request (303). The page model contains the metadata stored in the cloud storage pertaining to a scanned file (e.g., filename, file type, time stamp, and a pointer or reference to the associated URL). Note that the scanner 110 typically only communicates with Raven API 141, whereas the API communicates with the various cloud based processing and storage modules as needed. Significantly, however, once Raven API 141 passes the URLs to scanner 110, the scanner is able to upload the image files directly to cloud storage 145 (bypassing Raven API 141).

Having received the upload URL, the scanner 110 then begins uploading respective images to the API (304), which directs them to the appropriate location (URL) in cloud storage 145. Serverless function 143 is notified that upload has completed, and Raven API 141 is also notified (305).

While not illustrated in FIG. 3, the user is then provided an opportunity to combine and edit the individual pages, as described above in FIG. 2. For each selected editing function performed by the user, the scanner sends the editing instructions and associated image coordinates to the API, whereupon the API retrieves the image data from Google Cloud storage and processes the requested changes (e.g., cropping). The API then stores the processed image at a new assigned location (URL) in the cloud, and also returns the revised images to the scanner to be displayed as edited thumbnails. If additional pages are added to the data set, the user is given the opportunity to edit the new pages. All versions of all images are persisted in respective uniquely assigned URLs. This allows the user to quickly “undo” an edit or instantly go back and view a previous version of any image.

Subsequently, at 306, serverless function module 143 processes each image and creates a corresponding thumbnail image. In a parallel operation (307), the API calls a separate module (e.g., an OCR module 147 in FIG. 1) to perform optical character recognition on the uploaded images. The extracted text data may be stored, for example, in accordance with the OCR data representation standard. Next, at 308, the updated page data is sent to scanner 110 via, for example, a websocket interface. The Raven API then receives a request from the scanner to update the thumbnails (309), and the new document with an array of pages are received from scanner 110 (310).

It should be noted that Raven API 141 outsources creation of the thumbnails by invoking serverless functions 143. Upon creating each thumbnail, serverless functions 143 writes it directly into cloud storage 145 and provides the location information to Raven API 141, which then updates the page model to include a path to the thumbnail. In this regard, the scanner 110 may be configured to communicate with Raven API 141 through a socket implementation; if the scanner does not receive a thumbnail URL (or other expected parameter) in a timely manner, the scanner may query Raven API 141 directly. Stated another way, the default paradigm is to push messages; the failsafe backup paradigm is to pull them.

The finished PDF is then created by job processor 142 (at 311) from the OCR data and the previously processed images and stored in cloud storage 145. That is, once the final data set is complete, the user instructs the scanner 110 and the scanner instructs the Raven API 141 to send the data set to the selected destination. In response, the API retrieves the then current version of each page, and invokes the application (within cloud platform 140) to perform the computationally intensive function of assembling them into a single PDF file.

The transient image data (e.g., the various edited versions) still stored in cloud storage 145 may then be deleted to conserve overhead. Once the final PDF document is created for a finished data set, the previously extracted OCR text (stored, for example, within database 148) is embedded into (or layered onto) the PDF file, for example by associating a metadata file containing the text with the PDF file. As a result, users can effectively “search” the PDF document by searching the text inside the metadata file.

Depending upon the destination (query at 312), the system either stores the PDF in a cloud storage bucket for Raven Cloud (313) and sends an HTTPS response to scanner 110 (315), or sends to the PDF to the appropriate cloud service API (314) and sends a websocket response to scanner 110 (316).

It will be appreciated that serverless function module 143 communicates with Raven API 141 in multiple instances. For example, when each image is initially uploaded, serverless function module 143 notifies the Raven API 141, automatically creates a thumbnail, and provides the thumbnail URL to the Raven API 141. Also in response to an image upload, the Raven API 141 instructs the OCR module 147 (e.g., Google Cloud Vision or a third party processor) to commence OCR processing on the uploaded image. OCR module 147 retrieves the image from cloud storage 145, extracts the textual elements from the image, and returns the text to the API which updates the page model accordingly. If the user further edits the document or individual pages, the OCR function 147 is again performed for each revised image as necessary.

FIGS. 4A and 4B together provide a flowchart that includes and further elaborates on the procedures described in FIGS. 2 and 3. Referring first to FIG. 4A, method 400, as described in general above, begins with the user-selected scans being displayed (401). When the user initiates a scan (402), the scan setting values are sent to a scanner plug-in (403), which sends an appropriate request to the scanner module (404), which then in turn responds with paths to the locally stored images (405). A set of local thumbnail images are then displayed to the user based on the scanned pages (406).

The scanner 110 creates an object (e.g., allocates space) for each page and requests a page ID and upload URL for each object from Raven API 141 (407). Upon receiving the page IDs and upload URLs from scanner Raven API 141 (408), the full-scale page images are uploaded to cloud storage and directed to the assigned URLs (409).

When scanner 110 receives a socket response from Raven API 141 indicating that upload of the image files is complete (410), scanner 110 downloads (from specified URLs) the improved thumbnails generated by serverless functions 143 and uses them in place of the original thumbnails (411).

If the destination specified by the user corresponds to the USB drive (or similar flash memory component) (412), the scanner 110 simply requests that the cloud computing platform create the finished PDF document and then copies that file directly to the USB drive (413).

If the user indicates (e.g., through user interface 112) that she wishes to add pages (at 414), processing loops back to step 403. If no pages need to be added, processing continues with conditional 415 (FIG. 4B), which queries whether the user has completed page edits.

If the user requests edits (415), the edit commands are received by user interface 112 and performed (and the Raven API 141 is notified as appropriate) as shown in steps 422-427. That is, the user may remove pages (422), edit a page (423) (crop/rotate/zoom), reorder the pages (425), name or rename the document (426), and/or combine/separate the document (427). In the event that pages are cropped, rotated, or zoomed, the appropriate coordinates and/or edit instructions (e.g., percentage of reduction) are transmitted to Raven API 141 so that the changes can be implemented and subsequently reflected in the page model 182 (424), and processing loops back to step 410. When the document is named and/or its pages are combined or separated, the corresponding variables are stored for transmittal to Raven API 141.

If at step 415 it was determined that the user is done with page edits, the system initiates the sending of the final document to the appropriate cloud service API (419), and subsequently receives a corresponding web socket response from the API (421).

FIGS. 8A and 8B together present a signal diagram illustrating an exemplary method for operating the system of FIG. 1 in accordance with various embodiments. More particularly, this diagram contemplates interaction between eight entities: the scanner's user interface 112, the scanner 110, the Raven API 141, the job processor 142, the serverless functions module 143, cloud storage 145, OCR module 147, and the final destination 160.

Processing begins at 801, in which the user (via user interface 112) specifies the desired scan settings, and scanner 110 is sent a request to initiate a scan (802). Scanner 110 generates a set of images corresponding to the scanned document (803) and then displays the initial thumbnails based on those images via user interface 112 (804).

Next, scanner 110 requests that Raven API 141 create the appropriate page models (805), which are then created and stored by Raven API 141 (806). Scanner 110 also requests and receives specific storage URLs from Raven API 141 corresponding to the scanned images (807). Scanner then directly uploads the images to cloud storage 145 based on those URLs (808). Once upload is complete, an associated event (809) is received by serverless functions 143, which then notifies Raven API 141 of the completed upload (810), which in turn notifies scanner 110 (811).

Serverless functions module 143 generates and stores a set of thumbnails in cloud storage 145 (812), and job processor 142 requests and receives OCR data from OCR module (e.g., Google Cloud Vision) 147 (813). The OCR data may be stored in a variety of locations, but in one embodiment is stored within the pages model itself by Raven API 141.

Scanner 110 then downloads the created thumbnails from cloud storage 145 via Raven API 141 using the communication path shown (814). The updated thumbnails are then displayed via user interface 112 (replacing the initially displayed set of thumbnails) (815).

Next, the user may be allowed to specify page edits, as detailed above. If the user selects any such page edits, then scanner 816 is notified, which in turn sends the appropriate set of page edit parameters to Raven API 141 (817), which modifies the associated page models (818) and perform the required image processing to accomplish the page edits requested by the user (819).

The processed images are then stored in cloud storage 145 (820), which then notifies scanner 110 that upload has completed via serverless function module 143 and Raven API 141 (signal flow 821, 822, and 823).

Serverless function module 143 then automatically creates new thumbnails for each of the revised pages (824). Those thumbnails are then downloaded by scanner 110 via Raven API 141 (825) and displayed on user interface 112 (826).

Referring now to FIG. 8B, editing continues as necessary until no more edits are required, and the user indicates, via user interface 112, that the document is ready to be completed and sent to the destination (827). A request is sent to scanner 110 (828), which then notifies Raven API 141 (829), which in turn notifies job processor 142 (830).

Job processor 142 requests and receives page models and OCR data from Raven API 141 (831), then requests and receives final page images from cloud storage 145 (832). This information is then used by job processor 142 to generate a final, searchable PDF file (833). Job processor 142 then sends the finished PDF file to destination 160 (834) and notifies scanner 110 through Raven API 141 (835 and 836), using a method that depends upon the nature of final destination 160, as described in greater detail above.

In summary, what has been described are improved, easy-to-use, cloud-based systems and methods for scanning, securely storing, managing, and retrieving digital documents.
